Treatment of injecting TreeAzin® (azadirachtin) or IMA-jet® (imidacloprid) into the trees to kill beetle larvae inside the trunks will happen until late July.
Even with healthy ash trees being treated, the city expects all of Winnipeg’s ash trees will eventually die due to the beetle over the next 10-20 years.
The treatments are just being done to preserve the healthy portion of Winnipeg’s urban canopy to allow the City to proactively manage tree removals.
“It’s important to be proactive in slowing the mortality of our ash trees,” said Kerienne La France, supervisor of Urban Forestry Technical Services in a statement.
“We are selecting the best of the ash trees on public property for these injections, so we get the best value out of the treatments.”

• 5 (Chalmers)
